Title: Stabilised securing ring for radial tyre - with elastic layer over metal rings in tyre walls
Inventor: TIEMANN REINHARD DIPL ING
IPC: B60C15/06
Filed: 1974-03-18
Abstract: The edge of the tyre wall is provided with a steel securing ring as normal while a rubber insert layer is provided on the side of the ring nearest the wheel rim.

Title: Supervisory circuit for single phase synchronous motor - using two comparators and one limiter circuit
Inventor: SCHOLLENBERGER LOTHAR
IPC: H02H7/08
Filed: 1974-03-29
Abstract: A resistor is provided in the phase lead to the motor and one side connected to one input of a first comparator, whilst the other side is connected to the limiter circuit. The second limiter input is connected to the neutral lead, and the limiter output is connected to the second input of the comparator. The comparator output is evaluated in an integrating circuit, and a further comparator, or level detector, used to operate an alarm circuit.

Title: IC engine speed governing device - depends on lubricating oil pressure via hydraulic servomotor affecting governor spring setting
Inventor: ZBIKOWSKI GERHARD DIPL ING
IPC: F01M1/22
Filed: 1974-06-20
Abstract: I/C machine speed governor, working dependent upon the lubrication oil circuit pressure, with a governor with centrifugal weights and a hydraulic servo-motor with control slide valve and sequence piston to set up a nominal speed. The hydraulic servo-motor receives pressure oil from a pump not in the lub. oil circuit, and whose sequence piston sets up the speed governor control spring tension to give the nominal speed required. When the engine lub. oil pressure drops below a level consistent with the nominal speed, the feed pipe for the servo-motor oil is throttled dependent upon the extent of the sequence piston pressure, so that despite retention of the position of the control slide valve (15) the sequence piston (16) under the effect of the governor spring (14), adopts a position for reduced speed.
